Ingredients higher up in an ingredient list are typically present in a larger amount. Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture. Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%. It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier. Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%. A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions. Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum. Topically, glycerin does several things at once: Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3. Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin. This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products. Just know very high concentrations (>40%) can feel tacky in low humidity. Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine. Oryza Sativa Extract comes from the rice grain, Oryza sativa. Rice extract has wound healing, antioxidant, anti-inflammatory, and hydrating properties. Rice grains contain numerous antioxidants which may help with anti-aging, such as vitamin E. Antioxidants help stabilize free-radical molecules. Unstable free-radical molecules may damage your skin cells and accelerate signs of aging. A study from 2002 found rice to help increase the rate of wound healing. The same study found an improvement of skin barrier function in the patients after taking rice baths. Numerous in-vitro studies have found rice water to help decrease sun damage by increasing collagen production and inhibiting the process of tyrosinase. Long story short- tyrosinase is an enzyme that controls melanin production. Our bodies start producing melanin (AKA tanning) when exposed to UV radiation to protect against damage. Rice water is found to partially block this process. Though more research is needed on rice's ability to help with UV protection, recent studies seem promising. Wondering why rice is hydrating? The protein in rice have emollient properties. Emollients create a barrier on the skin to trap moisture in, keeping your skin moisturiz
